8. What happens if you increase the distance between the objects?

Answer 1

A positive F indicates a repulsive force — the charges push each other apart (q1·q2 > 0).
If both charges are weak (small magnitude), the electric force is correspondingly small, since F ∝ q1·q2.
Increasing the distance reduces the force according to the inverse-square law, F ∝ 1/r^2 (e.g., doubling r quarters the force).
